I made the mistake of resetting my ENV variables for HOME and HOMEDIR – which resulted in
a) My DOS prompt not being able to launch
b) My environment variables (Advanced Settings) not being able to launch.
So -I could not go back and DELETE the ENV variables that I had incorrectly set.
The workaround is to launch the following EXE
This should launch the ENVIRONMENT Variables configuration screen. Now, you can delete the incorrect variables – and you should be back in business.
